Rosewill LIGHTNING Series 1300W 80 Plus Gold Power Supply
MINT condition; only used for a few days;
With 5 years' warranty (will provide original invoice from Amazon)

Price: $170 + shipping or best offer (also accept BTC, LTC, FTC).  (Amazon/Newegg price: $220).
Ship from zipcode (37203), USA. Please PM me for international shipping.

More than enough to support 4x 7970 cards (overclocked). Runs very quiet and stable. Manufactured by SuperFlower, one of the best OEMs. even better than Seasonic 1250w in my experience.

Bought new ~2 months ago for my second rig, but didn't have enough space to host that machine.
It was only used for a few days for testing and then had been in box ever since.

You have to pay escort if needed. (I generally participate in the BTC/LTC/FTC community by answering technical questions).
Thanks.
